| Abstract: | In order to meet the needs of processing timeliness,format standardization and product richness of massive strong motion observation data of National Seismic Network,a strong motion data processing system with functions of rapid data collecting,processing and archiving is developed,which is compatible with many types of strong motion observation stations. It is capable of providing a seismic waveform human-computer interaction data processing interface to preprocess the acceleration record,analyzing the acceleration event waveform data,and calculating various parameters of ground motion,including peak ground acceleration(PGA),peak ground velocity(PGV),peak ground displacement(PGD),instrument intensity,duration,Fourier spectrum,response spectrum and triple spectrum,etc. It also can export metadata and seismic record waveforms,and archive and store all kinds of data. The system is characterized with platform unity,function integration and data completeness,and will play an effective role in daily data processing and management,earthquake emergency,earthquake damage assessment and scientific research. |
